Post-dural-puncture headache (PDPH) is a complication of puncture of the dura mater (one of the membranes around the brain and spinal cord). [3] The headache is severe and described as "searing and spreading like hot metal", involving the back and front of the head and spreading to the neck and shoulders, sometimes involving neck stiffness .
Serious complications of a properly performed lumbar puncture are extremely rare. [4] They include spinal or epidural bleeding, adhesive arachnoiditis and trauma to the spinal cord [10] or spinal nerve roots resulting in weakness or loss of sensation, or even paraplegia. The latter is exceedingly rare, since the level at which the spinal cord ...
In adults, the spinal cord terminates around the level of the disc between L1 and L2, while in neonates it extends to L3 but can reach as low as L4. [16] Below the spinal cord there is a bundle of nerves known as the cauda equina or "horse's tail". Hence, lumbar epidural injections carry a low risk of injuring the spinal cord.
There are no specific signs or symptoms that can indicate meningitis, and a lumbar puncture (spinal tap) to examine the cerebrospinal fluid is recommended for diagnosis. [47] Lumbar puncture is contraindicated if there is a mass in the brain (tumor or abscess) or the intracranial pressure (ICP) is elevated, as it may lead to brain herniation.
A spinal CSF leak can be caused by one or more meningeal diverticula or CSF-venous fistulas not associated with an epidural leak. [6] [7] [8] A spontaneous spinal cerebrospinal fluid leak may occur sometimes in those with predisposing heritable connective tissue disorders including Marfan syndrome and Ehlers–Danlos syndromes.
Therefore, a lumbar puncture ("spinal tap") is recommended to obtain cerebrospinal fluid if someone has symptoms of a subarachnoid hemorrhage (e.g., a thunderclap headache, vomiting, dizziness, new-onset seizures, confusion, a decreased level of consciousness or coma, neck stiffness or other signs of meningismus, and signs of sudden elevated ...
Though now considered a cult classic, it turns out that This Is Spinal Tap was not an easy movie to make.. The 1984 favorite, which stars Christopher Guest, Michael McKean, Harry Shearer and Rob ...
Lumbar puncture ("spinal tap") is the procedure to obtain CSF. The VDRL test of the CSF is a common test for making a diagnosis of neurosyphilis. A positive VDRL test in the presence of neurological symptoms is sufficient to confirm a diagnosis of neurosyphilis. [4] However, a negative VDRL result does not rule out neurosyphilis.
